A glass of wine here and there isn’t bad. In fact, it may protect against heart disease. But it’s the two, three or more glasses that may be doing a number on your waistline and health. A typical drink — 5 ounces of wine, 12 ounces of light beer or a shot of 80-proof liquor — contains about 110 calories. Two to three drinks a day adds up to nearly 2,000 extra calories per week. But more important than calorie content is alcohol’s effect on the body’s hormones.
